Solution Overview

Problem

Current remote control systems for model vehicles suffer from the 'Wrong Model Syndrome' where selecting the wrong model can lead to crashes, and complex signal manipulation in transmitters increases the risk of errors, especially with systems like Weatronic where data is stored in both transmitter and receiver.

Innovation Solution

Implementing a distributed embedded control system architecture using the CAN protocol, where input signals are transformed into digital messages with unique identifiers, allowing each device to select the necessary signals, simplifying transmitter design, and enabling the same transmitter to be paired with multiple models without modification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If model specific data is stored in the transmitter, then the transmitter can control multiple models, but selecting the wrong model can lead to crashes (Wrong Model Syndrome)

Engineering Contradiction:
Improveability to control multiple modelsVSAvoidrisk of crashes due to wrong model selection
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the model identification data into two parts: a first part stored in the transmitter and a second part stored in the receiver. The transmitter only transmits the first part, while the receiver stores the second part and uses it to verify model identity. This segmentation eliminates the Wrong Model Syndrome because the receiver's stored second part acts as a unique identifier that prevents mismatched model control, while still allowing the transmitter to control multiple models by storing only the first part of each model's identification data.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If complex signal manipulation is implemented in the transmitter, then control functionality is enhanced, but the risk of errors increases

Engineering Contradiction:
Improvecontrol functionalityVSAvoidrisk of errors
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent extracts the model verification function from the transmitter and places it in the receiver. The receiver stores the second part of model identification data and performs verification by comparing received data with stored data. This extraction reduces the transmitter's complexity and error risk while maintaining enhanced control functionality, as the receiver handles the critical verification task that prevents errors.

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If data is stored in both transmitter and receiver, then model identification accuracy is improved, but system complexity increases

Engineering Contradiction:
Improvemodel identification accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments model identification data into two parts distributed between transmitter and receiver. The transmitter stores the first part and transmits it, while the receiver stores the second part and performs verification. This segmentation improves model identification accuracy by enabling verification at the receiver, while managing system complexity through a clear division of responsibilities and a standardized communication protocol for exchanging the segmented data.

Inventive Principle:
Principle #1Segmentation
